RE: [SLUG] Redundant Web Servers


Well, we've solved the problem, and it works perfectly....

With much thanks to all the SLUGgers (and squid-ers) that gave
suggestions, we presented a plan to marketing that was almost
foolproof....

And we costed it at approx. $200k initially, plus another $50k
recurring costs....

They saw our point...:-)
